I realised over the years that on a 14 inch blade only the firts 2 inches are made of decent abrasive...
Is that because there are more fibre the closer you get to the arbor or because no matter the constant rpm of the saw a 10 inch blades has much less inch per minute of abrasive working on the surface... 14 x 3.1416 x rpm = ipm when it's reduced by 40% and fibers are added...

Over the years we tried so many brands even the walter representative made me try his whole assortment with limited failure or success. Add to that that some (most) cheaper blades are of poor quality and reinforcment inside is not always center and never cut straight, i have a home made saw driven by a 5 hp motor wich work best with mid priced blades (1/4 x 6 flat and straight when blade is worn less than 10 inches, or 3/8 x 2 1/12 flat cold rolled 4 stacked).

Performnce wise, not bad! but the dust.... I plan to go dry cut but fear the noise...
